Full build question with worldcrawl mod

[Riftweaver]

what would be an ideal hero+4mercenary +1companion(for quests) party that could survive with worldcrawl? things get so crazy later on with the endless mythic demons having stupid high AC that even with using toybox to be immortal (or just having stupid high stats and every buff in exsistance), it takes forever to kill things. i want to play some sort of demon path playthrough but i dont want to buff cheat if i can avoid it.
